Hi

* locality - Nave de Santo António - Serra da Estrela - PORTUGAL
* date - 2007.09.02
* size - 11 mm (large fly)
* habitat - openland at 1500 m
* substrate - on ground


I found this fantastic tachinid almost in the same place I caught the Bauhmaeuria microps.


EDIT---> Title changed from "Tachinidae - Goniinae ?" to "Tachinidae - Trixa conspersa" and then to "Tachinidae - it was Trixa sp. (unknown genus.or maybe an Estheria??)" and"Tachinidae - Estheria picta (from Nave de Santo António)"

I would say Trixa cf. conspersa

Medium fly does not equal 6 mm.
Trixa is much larger.
SO I go for the medium-size.

I was checking my notes in the size of the fly.
It has 11 mm! Sorry for the mistake. I will edit right now!

Well, that's good news, then there's little doubt this is Trixa.
Quite Oestridae-like Tachinidae

So there is no room for doubts that this is Trixa conspersa, right?

Unless it is a very rare species, it must be Trixa conspersa. That's why the cf.

By the way, it is Dexiinae - Dexiini, not Goniinae (see title)

sorry for bother with this again... but if not a Trixa, could it be really an Estheria? Or never could be it at all? What would be the other possibilites if it wasn't a Trixa? Beware that Nave de St. António is rich in very rare species. (as it was already seen in 3-4 species waiting for species/or even genus name.)

The small antennae suggest Trixa ... but perhaps Theo thinks it could be a different species :)

No, it cannot be a Trixa because Trixa has always BARE arista [LOOK at the second photo please - it is very clear that arista is..], and the arista is clearly hairy... SO what the heck is this Tachinid?? :)

Yes, I was having second thoughts as well on Trixa, for another reason: the parafacial is hairy. It is bare in Trixa.

So this really is a Estheria.
And now we know what to look for: the crossvein r-m is darkered. Moreover, the humerus is clearly yellow.

So it is Esheria picta

Finally a result I am happy with....
